Severe storms were expected Tuesday evening across Central Maryland, some bringing wind gusts of up to 60 mph, according to the National Weather Service.
A severe thunderstorm watch was in effect until 10 p.m. across the region, including Baltimore, Washington, D.C., the surrounding counties and the waters of the Chesapeake Bay.
Storm warnings were issued across Frederick County and near the Laurel area in Montgomery, Prince George's and Howard counties by early Tuesday evening. The storms were capable of producing 60 mph wind gusts, the weather service said.
High heat and humidity were fueling the storms, with a so-called "Bermuda high" pressure system pumping up moist air from the southeast. Temperatures reached at least 90 degrees at Baltimore-Washington International Thurgood Marshall Airport, and with high humidity, heat index values surged as high as 96 degrees.Copyright © 2014, The Baltimore Sun
